Industrial Wastes in Concrete Mixtures- A Review

Abstract: Concrete is the most widely used construction material. To meet the growing infrastructure and industrial needs, huge quantities of concrete is required, which, in turn, means that large volumes of natural resources and raw materials are being used for concrete production around the world. To eliminate or minimize the negative environmental impact of the concrete industry and promote environmental sustainability of the industry, the use of waste from industries as materials for concrete making is considered as an alternative solution for preventing the excessive usage of raw materials. The wide availability of industrial wastes makes them a suitable and dependable alternative for aggregate in concrete, wherever available. In this paper, an attempt is made to present a state of the art review of papers on replacement of aggregates and fillers by industrial waste. This paper reviews the possible use of industrial wastes such as sludge wastes from marble cutting industries, sewage treatment plants, water treatment plants, paper industries etc as aggregate in the concrete industry. It aims to promote the idea of using these wastes by elaborating upon their mechanical properties. This summary of existing knowledge about the successful use of industrial wastes in the concrete industry helps to identify other existing waste products for use in concrete making. From this identification by industrial and civil engineers, significant achievements can be attained. Keywords: industrial waste, aggregate, cement, concrete.
